Python 2.7 App executing as CGI instead of WSGI on App Engine

The following code generates a CGI method instead of WSGI as indicated in the log below. Is this the normal execution for a WSGI app on the dev server? If not what needs to change to get the application to execute as WSGI?

main.py

import webapp2
import wsgiref.handlers
import logging
from google.appengine.api import users


class HomeHandler(webapp2.RequestHandler):
    def get(self):
        self.response.out.write("Hi World")

app = webapp2.WSGIApplication([
    (r'/', HomeHandler),
], debug=True)

app.run()

app.yaml

application: WSGITEST
version: 1
runtime: python27
api_version: 1
threadsafe: yes

libraries:
- name: webapp2
  version: latest

handlers:
- url: /.*
  script: main.app

First, you should remove this line of code because it's incorrect:

app.run()

As written in my comment and well pointed out by aschmid00, could be an old debug statement.

this log is a hardcoded string: 

/usr/local/google_appengine/google/appengine/tools/dev_appserver.py:
 1622      sys.modules['__builtin__'] = __builtin__
 1623  
 1624:     logging.debug('Executing CGI with env:\n%s', repr(env))
